IMPROVEMENT IN DRIVEN WELLS.

Specification forming part of Letters Patent No. 140,963, dated July 15,1873; application filed J une 30, 1873.

.To all whom it may concern:

Be it known that I, GEORGE W. STOEER, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Apparatus for Forming Driven Wells; and do herebydeclare that the' following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing making a partof this specification, in which- Figure 1 is a perspective view of mystrainer-tube with the strainer removed. Fig. 2 is a side elevation ofmy improved strainer complete, and Fig. 3 is a vertical central sectionl of the same.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to prevent derangement and obstruction ofthe strainer of a driven well-tube While the same is being forced intothe ground; and it consists principally in the means employed forsecuring the inner wire to or upon the periphery ofthe tube,substantiallyas and for the purpose hereinafter specified. Itconsists,further, in combining with said strainer-wire a second wire Woundspirally around the same, and connected therewith by means of corrugatedstrips of thin metal, substantially as and for the purpose hereinaftershown.

In the annexed drawing, A represents a metal tube provided, within oneend, with a screw-thread, a, and at its opposite end with a solid metalhead, B, which has a slightly greater diameter than the exterior of saidtube, and at :its sides extends downward and inward in a curve so as toform a point, as seen. At suitable equidistant points the walls of thetube A are provided with radial openings ct, whileA upon and around itsperiphery is wound spirally a wire, C, the ends of which are secured toor upon the ends of said tube.

At equidistant points radially two or more strips of thin sheet metal,D, are placed vertically upon the wir'e C, and crimped or corrugated soas to cause them to conform to the surface of said wire and ill thegrooves or channels left between the coils of the same, said stripsbeing secured in place by solder or other suitable means. A second Wire,E, is now coiled around' the tube, its coils resting within the groovesin the strips D, which are formed by and conform to the depressionsbetween the coils of the first wire C, said wire E being in turnsoldered or otherwise attached to said strips.

As thus constructed, it will be seen that the metal strips D separatethe inner and outer coils of wire sufficiently to enable water to passfreely through the same, While from their connection with said wires allliability to the derangement of the latter during the process of drivingthe tube is avoided, and the relative positions of parts areinsured.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1ST- 1. In combination with the perforated tube A andcoiled Wire C, the corrugated strips D placed upon and secured to saidparts, subhave hereunto set my hand this 24th day of June, 1873.
